Webb63 rader · Ultimate tensile strength (also called UTS, tensile strength, TS, … The theoretical strength of a solid is the maximum possible stress a perfect solid can withstand. It is often much higher than what current real materials can achieve. The lowered fracture stress is due to defects, such as interior or surface cracks. One of the goals for the study of mechanical properties of materials is … Visa mer When a solid is in tension, its atomic bonds stretch, elastically. Once a critical strain is reached, all the atomic bonds on the fracture plane rupture and the material fails mechanically. The stress at which the solid fractures is the … Visa mer The stress-displacement, or $${\displaystyle \sigma }$$ vs x, relationship during fracture can be approximated by a sine curve, Visa mer • Strength of materials • Fracture mechanics • Solid mechanics • Stress (mechanics) Visa mer
